• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky danh ma hoi. hieu ((va cam) OR (va cao)) ((xuc ban) or (quoc ban)) thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky danh ma hoi. hieu ((va cam) OR (va cao)) ((xuc ban) OR (quoc ban)) thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky danh ma hoi. hieu ((va cam) OR (va cao)) ((xuc ban) or (quoc ban)) thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky danh ma hoi. hieu ((va cam) OR (va cao)) ((xuc ban) or (quoc ban)) thanh hai cua tre*.
